Whether with an insulin pump or with mul-tiple daily injections, the diabetic patient trained in FITis able to dose his insulin on the basis of actual fuctionso that he achieves near-normoglycemia and the freedom toeat when, what and how much he wants. Previous diabetes eduction programs have adaped thepatient’s lifestyle to the conditions of therapy. The goalof FIT is to adapt the therapy to the lifestyle of the pa-tient.
